Introduction
The DWL-G680 has the newest, strongest, and most advanced security features available
today. When used with other 802.11 WPA/WPA2 (Wi-Fi Protected Access/Wi-Fi Protected
Access 2
TM
) and 802.1x compatible products in a network with a RADIUS server, the
security features include:
WPA/WPA2: Wi-Fi Protected Access/Wi-Fi Protected Access 2
TM
which authorizes
and identifies users based on a secret key that changes automatically at regular
intervals.
WPA/WPA2
uses
TKIP
(
Temporal Key Integrity Protocol
) to change
the temporal key every 10,000 packets (a packet is a kind of message transmitted
over a network.) This ensures much greater security than the standard WEP
security. (By contrast, the older WEP encryption required the keys to be changed
manually.)
802.1x: Authentication
which is a first line of defense against intrusion. In the
authentication process, the Authentication Server* verifies the identity of the
client attempting to connect to the network. Unfamiliar clients would be denied
access.
For home users that will not incorporate a RADIUS server in their network, the security
for the DWL-G680, used in conjunction with other WPA/WPA2-compatible 802.11
products, will still be much stronger than ever before. Utilizing the
Pre Shared Key
mode
of WPA/WPA2, the DWL-G680 will obtain a new security key every time it connects
to the 802.11 network. You only need to input your encryption information once in the
configuration menu. No longer will you have to manually input a new WEP key frequently
to ensure security. With the DWL-G680, you will automatically receive a new key every
time you connect, vastly increasing the safety of your communication.
* Not all servers can provide Authentication.
